Sor is one the creative geniuses behind the collective Black Acid. He takes responsibility for the vocals, and for much of the productions. Last year he was confronted with hearing loss, which forced him to take creative measures. The use of synthesizers, with their typically rich sound, offered the solution and is now a regular feature in his work. In 2019 Sor signed at Dutch hip hop label Noah’s Ark and released his ‘Phonak’ EP (named after his hearing-aid), followed in 2020 by second EP Professor.
